Product Specifications

Technical details and manufacturing context for Gas Valve

Definition
A specialized valve component within Pulsation Dampener (Suction & Discharge) systems that precisely controls gas flow to manage pressure fluctuations, prevent backflow, and ensure stable operation of connected machinery by opening, closing, or partially obstructing gas passageways.
Working Principle
Operates through mechanical actuation (manual, pneumatic, or electric) to adjust the position of a closure element (ball, gate, or diaphragm) relative to the valve seat, thereby controlling gas flow rate and direction based on system pressure requirements and dampener operational needs.
Common Materials
Stainless Steel, Brass, Carbon Steel
Technical Parameters
  • Nominal pipe size indicating the valve's connection diameter (mm) Standard Spec
Components / BOM
  • Valve Body
    Main structural housing containing internal components and providing connection points
    Material: Stainless Steel
  • Closure Element Part
    Movable part (ball, gate, or diaphragm) that regulates gas flow by sealing against the seat
    Material: Stainless Steel
  • Stem Part
    Connects actuator to closure element for position control
    Material: Stainless Steel
  • Seat Part
    Stationary sealing surface that mates with closure element to prevent leakage
    Material: PTFE or Elastomer

Sizing Data Required
  • Maximum flow rate (m³/h)
  • System pressure (bar)
  • Gas density/viscosity

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Sticking or Binding
Cause: Accumulation of contaminants (dust, debris, moisture) on valve stem or sealing surfaces, or inadequate lubrication leading to increased friction and mechanical resistance.
Internal Leakage
Cause: Wear or degradation of valve seat or seal materials due to thermal cycling, chemical corrosion from gas impurities, or erosion from high-velocity gas flow over time.
Maintenance Indicators
  • Audible hissing or whistling sound indicating gas leakage around valve body or connections
  • Visible corrosion, discoloration, or moisture accumulation on valve exterior suggesting internal degradation or seal failure
Engineering Tips
  • Implement regular preventive maintenance including cleaning of valve internals and application of manufacturer-recommended lubricants to moving parts
  • Install upstream filtration to remove particulates and moisture from gas stream, and monitor gas composition to prevent corrosive chemical exposure

Compliance & Manufacturing Standards

Reference Standards
ISO 23551-1: Gas safety and control devices for gas appliances ANSI Z21.21: Automatic gas shutoff valves for gas appliances DIN EN 161: Automatic shut-off valves for gas burners and gas appliances
